And you have a curtain, and behind that curtain is a heavyweight. It can be any heavyweight from any point in time, they will be random and you'll have no knowledge of who it's about to be. And you have to pick a fighter to beat him. For arguments sake lets say your life rests on your guy winning the outcome of this fight. Who do you pick?
Muhammad Ali. Muhammad Ali is too intelligent for Tyson, Tyson can be outboxed, that's the thing. Also Muhammad Ali has dealt with bigger punchers than Tyson: Foreman and Shavers. Muhammad Ali would also beat Lennox Lewis and Larry Holmes.
I'd pick Audley and hope the guy behind the curtain was someone he'd fought before. 3(2) - 0 in rematches baby!!!
